HL-LHC Configuration Management
Keywords : HW Baseline, Naming, Parameters, Layout DB, Change Control
The HiLumi LHC Design Study (a sub-system of HL-LHC) is co-funded by the European Commission within the Framework Programme 7 Capacities Specific Programme, Grant Agreement 284404.
Slide2HL-LHC Configuration Management
This presentation addresses the configuration management of HL-LHC and places it in perspective of a future merge with LHC. Compatibilities, proposals and issues are presented.
It is structured as follows:LHC Project and LHC MachineHandling concurrently HL-LHC and LHCNames, parameters, layout, slots, HW BaselineActivity and HW Baseline/ParametersWhat’s nextS. Chemli - 2013-03-26
Slide3LHC Project and LHC Machine
LHC Project (prior to its installation) was handled through configuration management to allow
A clear view on the state of the project – in a HW Baseline, LHC Equipment Catalog for Parameters, Layout DB for MAD/XA common view on the state of the project – Approval of parameters and documents (PLC, TCC, LTC, LMC, Maric,…)LHC Machine (in operation) follows the same rules, with configuration management and change control (ECRs).Every step/stop is traced – changes from TS/LS to TS/LSS.

Slide4LHC Project and LHC Machine
Documents were stored in the Hardware Baseline

Slide5Handling concurrently HL-LHC and LHC
Several aspects to consider:Names
Parameters of magnetsLayout drawingsFunctional positions - SlotsHW BaselineS. Chemli - 2013-03-26
Slide6Names
The Naming portal now covers all accelerators
S. Chemli - 2013-03-26
Slide7Names
Names have to be compatible with existing ones and properly declared in Naming, e.g. MQXF.
Proposal : Use Accelerators-naming.Service@cern.ch addressGet a reference person in the Magnets group with an overview of all the codesIssue : Might be necessary to update to 8 characters for the equipment codes. QA-WG issueS. Chemli - 2013-03-26
Slide8Parameters
From Isabel’s presentation to HLTC

Slide9Parameters
As a reminder, the equipment catalogue is fully integrated into the
Layout and actively used today by operations, MAD generation files, ELQA campaigns, HWC testsProposal : Use the LHC equipment catalogueIssue :Approve the parameters S. Chemli - 2013-03-26
Slide10Layout Drawings
These are conceptual drawings LHCLSX and LHCLSXG, LHCLSS, LHCLSA and electrical drawings LHCLSD, cryogenic P&ID LHCLSQR
These names are the ones of the current LHC machine.Proposal : Use new names for the drawings with a lifetime up to LS3Issue : Maintain several sets of drawings: LHC vs HL-LHC, Multi-branching inside HL-LHCMaintain and modify by hand (trial and error), maintain and modify with a DB input (with approval and versioning)S. Chemli - 2013-03-26
Slide11Functional Positions - Slots
Functional Positions, Types, and Regions are going to change heavily. Still some internal mechanisms in the Layout DB help in checking integrity
of the data.Proposal : Use the layout DB for defining configuration of assemblies, e.g. LQXDA, functional positions e.g. LQXDA.3R5, regions e.g. 4R5Introduce validity dates for all elements handled in the layout DBIssue : Availability of such a modification is mid-LS1 or end-LS1Checking and re-checking coherence once data is updatedS. Chemli - 2013-03-26
Slide12HW Baseline
The HW Baseline is the place were long-term documents are stored. By long term documents, it is meant
Procurement (Technical Specifications for MS, IT, PI)Engineering Specifications, Change RequestsManufacturing (Drawing folders, Assembly Procedures, Test Procedures, Installation Procedures, etc.)Proposal : Rename nodes with a ‘Current Machine’ prefixDuplicate the nodes with ‘HL-LHC’ prefixThis eases the attachment to the activity structure (see next slide)Issue:The overall baseline becomes unreadableRe-work the baseline to suppress nodes at LS3S. Chemli - 2013-03-26
Slide13HW Baseline
This is a sample of the HW Baseline with the first upgrade project
S. Chemli - 2013-03-26
Slide14Activity and HW B
aseline/Parameters
To be able to continue storing information on the official systems but be able to find HL data without navigating
From Isabel’s presentation to HLTCS. Chemli - 2013-03-26
Slide15Activity and HW Baseline/Parameters
Parameters will be a mirror
of the LHC equipment catalogueDocuments will be updated automatically by any document introduced in the hardware Baseline with the same equipment code but you will be able to create documents that are not “compulsory” and that will have a normal EDMS numbering
MQXF
From Isabel’s presentation to HLTC
S. Chemli - 2013-03-26
Slide16What’s next
Getting an overview on the needed codes (Naming) : correctors, dipoles, cavities, DFB…, and work with all the link persons from the groups and the PE. Already started with MQXF for example.
Prepare the HW baseline by separating nodes where adequatePrepare the set of drawings handling the conceptual layout. And define methodology with the layout DB.Collect the parameters of the magnets approved by the PLC and insert in EDMSS. Chemli - 2013-03-26
